Abstract
In response to the study by Tian et al. on the immunogenicity of COVID-19 vaccines in patients with autoimmune hepatitis, this letter commends the authors' contribution but highlights a critical omission: the lack of details regarding their search strategy. Reproducibility, as defined by the National Academies of Sciences, Engineering, and Medicine, is essential in systematic reviews (SRs) to ensure consistent results and transparency. Incomplete reporting, particularly in search strategies, compromises the reproducibility and integrity of SRs. To address this issue, it is recommended that future authors include detailed search strategies and consult the PRISMA-S Extension checklist for guidance on proper reporting.
